Unless you *REALLY* want to go totally bare metal and build your tools and environment from the ground up as a learning exercise, you should probably grab StarterWare from TI: http://www.ti.com/tool/starterware-sitara ...and the compiler of your choice (likely TI's Code Composer Studio or gcc setup for cross-compiling). It has a build environment, (some) hardware abstraction, and a variety of example code. Once you get something running you can go as close to the bare metal as you want, but getting a complex SoC like the AM3359 up and running (low-level hardware initialized properly so you can do things like talk to DRAM and send serial messages out the UART) is a non-trivial task. I'd start with their examples and tweak the startup code if/when you have the need. -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
